180 Degree Elbow
180 Degree Elbow
A 180-degree elbow, also known as a U-bend or return bend, is a pipe fitting that allows the pipeline to make a complete 180-degree turn, essentially reversing the flow direction. These elbows are commonly used in a variety of industries and applications where a smooth, continuous flow path is necessary.
